SPEUIFICATION forming part of Letters Patent No. 765,088, dated July 12,1904.

Application filed January 6, 1904:. Serial No. 187,944. (No model.)

To all whom, it nuty concern.-

Be it known that I, J osnrrr E. LEMYRE, a

citizen of the United States, residing'at Manchester, in the county ofHillsboro and State of New Hampshire, have invented new and usefulImprovements in Bobbins or Filling Carriers and Feeders for Looms, ofwhich the following is a specification.

This invention relates to an improvement in the construction of bobbinsor filling-carriers'pa'rticularly adapted to be held in a revolvingfilling-carrier feeder for a loom, and especially refers to theconstruction of the bobbin or carrier.

The primary object of the present invention is to overcome well-knownobjections now existing in this class of bobbins or fillingcarriers andprevent them from rotating in the feeder or becoming misplaced and alsoto reliably retain them in such position in the feeder as to besuccessively engaged by the ejecting mechanism and properly disposed inthe shuttle.

The invention consists in the construction and arrangement of the partswhich will be more fully hereinafter set forth.

In the drawings, Figure 1 shows an end elevation of a portion of abobbin or filling-carrier feeder, together with a pusher or ejectingmechanism embodying practically the ordinary construction with slightchanges, and illustrating a number of the improved bobbins'orfilling-carriers disposed in the feeder. Fig. 2 is a detail perspectiveview of the head extremity of the bobbin or filling-carrier. Fig. 3 is alongitudinal vertical section of the bobbin or filling-carrier shown byFig. 2. Fig.

4 is a detail perspective View of a part of a shuttle with a portion ofthe bobbin or fillingcarrier therein.

Similar numerals of reference are employed to indicate correspondingparts in the several views.

The bobbin or filling-feeder is composed of a notched head or disk 1, asin ordinary devices of this class, at one end of a sleeve 2, mounted ona stud 3, and the notches or peripheral slots 4 are radially disposedand have opposite straight parallel sides. The notches or slots 4 openoutwardly through the periph- 5 cry of the head or disk 1, andcooperating with the latter is a pusher 5, mounted on a stud 6 andhaving at its free end an ejecting or expelling head 7, provided with adepending pin 8. On the hub of the pusher 5 is secured an arm 9, whichcarries a movable member 10 at its free end, having an upper curved edgeagainst which the bobbins or filling-carriers are pressed, as in theusual arrangement of this class and readily understood in the art. 0

The shuttle 11 (shown to illustrate the application of the invention)has the usual jaws 12, one of which is shown by Fig. 4, and a bridge 13.It will be understood that shuttles applied with other analogousattachments may be equally well used.

The bobbin or filling-carrier 14: has the usual head 15, which inaccordance with the features of the invention is preserved in truecylindrical contour Without interruption by the formation of straightsurfaces thereon, and projecting from the end of the head areholding-bosses or enlargements 16, separated by an intervening slot 17,the outer side edges 18 of said bosses being straight and parallel toeach other. The straight side edges 18 form secant surfaces for guidingand holding the bobbin or filling-carrier when inserted in the head ordisk 1 without requiring the use of radially-projecting pins in saiddisk and permitting the bobbin or carrier to be inserted in its notch orslot without requiring a precise arrangement, or, in other words, thebobbin or carrier can be turned in opposite directions for placement inthe head or disk 1 as long as the secant surfaces provided by the outerstraight side edges of the bosses or enlargements 16 are in line withthe opposite walls of the notch or slot in the disk in which it isdesired to insert the head of the bobbin or carrier. The slot 17,extending between the bosses or enlargements 16, provides means for thereception of the pin 8 on the head of the pusher, and by having saidslot extend fully through the bosses or enlargements either end thereof95 may be engaged by the pin. The pin 8 holds the bobbin against turningor revolving after the head 15 is brought to bear on the movable member10 to maintain the bobbin-head in a proper position for introduction inthe shuttle; but for the pin 8 the bobbin would turn or revolve on themember 10 after the head 15 had been cleared from the slot 4.Surrounding the head 15 are metallic rings 19, which are for a purposewell understood in the art, and the present improvement embodies asimple securing method for said rings, which consists in bending theterminals 20 thereof at an angle and driving them into the head, asclearly shown by Fig. 2. Before securing the rings as set forth they aretightly drawn around the head 15 until the bent terminals are in closerelation, and said terminals are then secured as set forth.

Adjacent to the headthe body of the bobbin or filling-carrier is formedwith oppositely-disposed slots 21 for cooperation with adetector orfeeler, and in the presentinstance the bobbin-body has applied over saidslots a metal sleeve 22 to serve as a strengthening means, the innersurfaces of the opposite extremities of the sleeve being thread ed, asat 23, to secure and hold said sleeve against movement. The sleeve is ofthin metal and does not form material projection on the bobbin orcarrier, and therefore will not interfere with winding the fillingthereon.

The sleeve 22 is slipped longitudinally over the smaller end of thebobbin and moved toward the head 15, the end of the sleeve nearest thehead being first caused to engage and pass screw-threads surrounding thebobbin adjacent to the terminals of the slots 21, which are farthestfrom the head. After the advance end of the sleeve has passed inwardbeyond. the said screw-threads the rear terminal of the sleeve isbrought into engagement with the same threads and simultaneously theterminal of the sleeve nearest the head 15 engages like screw-threadsnear the outer terminals of the slots 21, and by continuing to rotatethe said sleeve both sets of screwthreads are engaged fully by saidsleeve to secure the latter in place. When the sleeve is applied, theslots therein at diametrically opposite points are caused to coincidewith the slots 21. The opposite terminals of the sleeve arescrew-threaded solely, and by this means the part of the sleeveintermediate the ends will move over the portion of the bobbin havingthe slots therein'without obstruction.

From the foregoing description and a knowledge of the art to which -thisinvention pertains the advantagesof the construction of the bobbin orcarrier in the several particulars enumerated will be apparent, andwhile one form of disk 1 has been illustrated it will be understood thatthe use of the improved bobbin or carrier is not confined to anyparticular construction of disk. The ejecting mechanism is essentiallythe same as that well known in the art, except the head or hammer 7,carrying the pin 8, and the operation of such mechanism is well knownand need not be particularly herein set forth further than to explainthat the pin 8 is depressed into either end of the slot 17 between thebosses or enlargements 16 and the downward pressure of the head orhammer on the said bosses will cause each bobbin or carrier engaged tobe ejected or expelled from the feeder.

Having thus fully described the invention, what is claimed as new is 1.A bobbin or filling-carrier having a head of cylindrical form withbosses projecting from the end thereof and spaced apart by anintervening slot, the outer side edges of said bosses being straight andparallel to produce opposite secant surfaces, the slot-walls being alsoparallel with the said surfaces.

2. A filling-feeder having a head with a series of notches therein andexpelling devices including a pusher provided with a head carrying adepending pin, and a series of bobbins or filling-carriers each having ahead with bosses projecting from the end thereof, the bosses beingseparated by an intervening groove open at both extremities, the saidbosses having outer side edges forming secant surfaces.

3. A bobbin or filling-carrier having a body with oppositely-disposedslots, the body adjacent to the terminals of the slots having screw-
